Meanwhile, TSMC's 7nm process has been shipping since Q3 2018, and their EUV-based N7+ process is now in mass production. There's no question that TSMC is currently ahead of Intel both nominally and in all the important technical metrics. It's still entirely possible that Intel could re-take the lead if/when they get something post-10nm out the door, but that isn't going to happen this year. Intel's own CFO says it might take two more generations for them to regain the lead: https://www.tomshardware.com/news/intel-process-tech-lag-com...
Intel's current form of 10nm is roughly equivalent to TSMC's 7nm. What that basically means is TSMC is about a generation ahead.

So, to make this an apples-to-apples comparison: when did TSMC stop shipping new products on prior nodes? ;)
You can still go out and buy a new-production Ryzen 1600 AF chip right now, you know. AMD did not even finish releasing their 7nm lineup until basically a few weeks ago, Renoir products just started shipping last month.
Ice Lake actually beat the comparable AMD/TSMC chips to market by like, 8 months or something. They've been around in volume since like, november. I went to Costco before last thanksgiving and almost half the laptops had Ice Lake.
AMD can ship desktop processors sooner because they've architecturally managed to reduce the chiplet to smaller than the size of a phone SOC. Comparing apples to apples, or more specifically monolithic mobile processor vs monolithic mobile processor, TSMC isn't that far ahead.
Or for another data point, TSMC's big-chip 7nm yields are so bad that NVIDIA is disabling 15% of the processor on the Ampere GA100 even for the datacenter market that will be paying $25k a chip or something stupid.
TSMC is ahead, sure, but not as much as people want them to be. The ability to make phone SOCs and 70mm2 chiplets successfully doesn't mean they've got 7nm completely nailed.
Depends on which Intel 10nm you're talking about, and which TSMC 7nm. Comparing Intel's failed initial 10nm from Cannonlake against something that is in mass production on the TSMC side isn't exactly fair. With respect to the 10nm Intel product that you can actually buy, TechInsights has this to say: "Produced in Intel's new 10 nm 2nd Gen process that should offer comparable performance to TSMC’s 7 nm process"— and that's coming from the pros with electron microscopes who teardown these chips to reverse engineer process tech. Numbers reported elsewhere (eg. WikiChip) indicate that TSMC's 7nm allows for about a 15% smaller SRAM cell, and AMD's Renoir notebook processors seem to have about the same overall transistor density advantage over Intel's Ice Lake notebook processors.
And as far as I can tell, AMD's not even using the EUV 7nm process from TSMC yet.
